# Industrial Specification: Edge Preparation Unit

## 1. Technical Definition
A specialized component within an industrial system designed to prepare material edges for subsequent processing or assembly operations.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.0 mm material removal depth, 15-60 m/min feed rate, 1000-5000 RPM spindle speed**. Failure boundary: **Material removal depth exceeding 3.2 mm causes tool deflection &gt;0.05 mm, spindle torque exceeding 12 N·m at 5000 RPM, feed force &gt;450 N**, Mechanism: **Exceeding yield strength of cutting tool material (e.g., tungsten carbide σ_y = 4.5 GPa) leads to plastic deformation; excessive thermal loading (&gt;600°C) causes phase transformation in tool coating (TiAlN → TiO₂)**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Coolant flow rate dropping below 2.5 L/min at 0.3 MPa | 8 | Cutting tool thermal expansion exceeding 15 μm, resulting in dimensional inaccuracy &gt;±0.02 mm | Integrate redundant coolant pumps with flow sensors (accuracy ±0.1 L/min) and automatic switchover at 2.8 L/min threshold |
| Servo motor encoder resolution degradation below 0.001° angular precision | 8 | Positional error accumulation exceeding 0.1 mm over 10 cycles, causing edge chamfer angle deviation &gt;±0.5° | Implement dual absolute encoders with 0.0005° resolution and Kalman filter-based position validation algorithm |
